The Decompressor is a silver-gray color and appears to be made out of metal. It is cube shaped with two openings, one at the front and one at the back, for Wario to pass through. Two floor-level windows are on the front so that the player can see Wario getting recompressed. Yellow lights flash above the two openings and the windows. Wario in his normal form and evenenemies can pass through a Decompressor without any effect. Besides the Decompressor, Flat Wario can also change back into his normal form by touching water.
